Carburetor with starting fuel supply mechanism

A carburetor with a starting fuel supply mechanism which additionally supplies a starting fuel at the start of an engine, comprising:

• a choke valve in suction passages extending through a main body:
• and
• a starting fuel supply path disposed as a bypass of a main fuel passage to connect a float chamber to the suction passages. the starting fuel supply path being provided with an opening/closing valve opened by interlocking with the closing operation of the choke valve,
• wherein the starting fuel supply mechanism comprises valve opening/closing means having one end projecting to the suction passages and having the other end connected to a valve body of the opening/closing valve, and a valve body of the choke valve which performs the closing operation in the suction passages presses the valve opening/closing means while abutting on the one end of the valve opening/closing means, whereby the valve opening/closing means is moved to open the opening/closing valve of the starting fuel supply path, so that the starting fuel is prepared to be supplied and
• wherein the valve opening/closing means is a valve rod having a tip connected to the valve body of the opening/closing valve and having a base end provided with a valve body abutment portion on which a part of the valve body of the choke valve abuts and provided with a valve spring which urges the opening/closing valve in a valve closing direction, and the valve opening/closing means keeps the closed state of the opening/closing valve in a state where the valve body of the choke valve does not abut on the valve body abutment portion.
